Cheat Sheet

  1. Deductive Reasoning Basics -

    Deductive logic helps you draw certain conclusions by applying general rules to specific cases. For example, the classic syllogism "All mammals breathe air; whales are mammals; therefore, whales breathe air" shows how premises guarantee a conclusion (Stanford Encyclopedia of Philosophy). Practice structuring arguments this way to ace common sense quiz questions!

  2. Heuristics and Biases Awareness -

    Your brain uses shortcuts like the availability heuristic to fill gaps quickly, but these can lead to pitfalls (Tversky & Kahneman, 1974). Use the mnemonic "ABC: Always Be Checking" to remind yourself to pause and question initial judgments. Spotting these biases sharpens your everyday reasoning for questions for common sense.

  3. Estimation and Fermi Problems -

    Fermi estimation breaks complex guesses into simple components - like estimating the number of piano tuners by multiplying population, households, and tuner frequency. This approach teaches you to approximate effectively under uncertainty (University of California, Berkeley insights). Regular practice boosts your confidence when tackling quiz on common sense scenarios that lack exact data.

  4. Pattern Recognition Techniques -

    Spotting patterns is key in common sense trivia and trick questions, whether in sequences or everyday cues (MIT's cognitive science research). Try exercises like identifying the next number in a series (e.g., 2, 4, 8, ?) to train your brain. Familiarity with shapes, rhythms, and early exit strategies gives you an edge on common sense trick questions.

  5. Applying Mental Models -

    Mental models like Occam's Razor ("the simplest solution is often best") and first-principles thinking sharpen your decision-making (Charlie Munger's multidisciplinary framework). Keep a quick-reference list of models to deploy in any scenario for rapid clarity. Leveraging mental models turns everyday smarts into a systematic toolkit for any common sense quiz.
